dns/api.yaml: add missing record types

[rjw57]

Update the list of valid DNS record types to match the list documented at https://cloud.google.com/dns/docs/records.
In particular this was hurting people who were previously deploying DNSSEC key records via terraform.

Fixes hashicorp/terraform-provider-google#8897

If this PR is for Terraform, I acknowledge that I have:

• Searched through the issue tracker for an open issue that this either resolves or contributes to, commented on it to claim it, and written "fixes {url}" or "part of {url}" in this PR description. If there were no relevant open issues, I opened one and commented that I would like to work on it (not necessary for very small changes).
• Generated Terraform, and ran make test and make lint to ensure it passes unit and linter tests.
• Ensured that all new fields I added that can be set by a user appear in at least one example (for generated resources) or third_party test (for handwritten resources or update tests).
• Ran relevant acceptance tests (If the acceptance tests do not yet pass or you are unable to run them, please let your reviewer know).
• Read the Release Notes Guide before writing my release note below.

If the acceptance tests do not yet pass or you are unable to run them, please let your reviewer know.

Due to internal funding procedures it would be a fiddle to set up a Google project which could create real resources.

Generated Terraform, and ran make test and make lint to ensure it passes unit and linter tests.

I get a lot of go fmt problems apparently unrelated to this PR so I suspect I may be doing this wrong.

I get a lot of go fmt problems apparently unrelated to this PR so I suspect I may be doing this wrong.

But once I run make fmt, make fails, again due to reasons which appear unrelated to the PR:

There were a couple of build issues yesterday that were unrelated to this PR so let's do a new /gcbrun

LGTM in principle assuming tests pass :-)
